Abstract
A display device 10 including a supporting substrate 12, pixels arranged over the supporting substrate, and a member which is arranged on the light extraction side of a defective pixel 22b, the defective pixel being in a constantly non-lit state, the member being imparted with a light scattering property by the selective application of external energy. Preferably, disposed is a thermosensitive layer 24 which changes from a transparent state to a light scattering state when the layer is heated to a specified temperature or higher. An examination is performed for specifying the constantly non-lit defective pixel from among the pixels arranged over the supporting substrate. An external energy is selectively applied to at least one member arranged on the light extraction side of the defective pixel specified by the examination, thereby imparting the light scattering property to the member.
